I have got a set of Park tool cone spanners from Wiggle, http://www.ctcshop.org.uk/park-tools-do ... ne-wrench/ with the current discount they are less expensive they many of the alternatives.

I think the answer is already in this thread but there is also some confusion. I found this websites explanation useful http://www.sportsci.org/jour/9804/dps.html#downhill. You have to look at the earlier section for definition of the terms.

It can be seen on BBC iplayer for the next four days as well.

It is fine to leave the pump in the fuel bottle.

Yes, there is no problem with leaving the pump in the bottle. However, we recommend that the pressure is released when not in use. Do this by slowly unscrewing the pump, away from open flames, while holding the bottle upright.

I think seatpost getting stuck is just a problem in general, in theory CF should get stuck less as they don't corrode. Aluminium seat posts are good at getting stuck in steel frames if they are not occasionally removed and greased as both metals can corrode bonding them together.

In my case it had always been easy to get out before but I didn't need to adjust it for a year or more so a very small amount of corrosion in the steel frame caused it to jam.

Recently I got a carbon fibre seat post stuck in a steel frame, first I tried spraying GT85 (any penetrating oil will do) in to the seat tube via the bottle cage bosses and around the top and then sat the frame upside down. This did not work so after a few days of trying, I boiled a kettle of water and poured this over the seat tube avoiding the seat post and after a few seconds (~20 seconds) the seatpost came out easily, I think the oil inside might have helped lubricate it.
It is worth a try as the water is not hot enough to cause damage to the frame and the aluminium is a much better conductor than the carbon fibre so heats and expands faster.

If it does not work you can still try other methods but I was able to get the seat post out without damage to it or the frame. An old saddle can be used to provide leverage but with mine I could see the seatpost flexing so the amount of force I was prepared to try was quite low.

You can get a Bryton Rider 40 T which provides speed, cadence, heart rate and GPS in on package for £130. I will also work with power meters but any power meter is going to cost a lot more than the computer.

I have not used the Rider 40 but I have a Bryton Rider 30 T and I really like it.

I found this company which sell replacement seals and bearing for Hollowtech II bottom brakects. http://www.enduroforkseals.com/id227.html they claim to improve the sealing. I haven't used them and they are USA based but it looks interesting.

Would a cyclocross double chainset such Shimano CX50 be of help? It is 46/36 with a 110 BCD so I think the smallest inner ring you could fit would be 34.

Another update from the Daily Record who have a journalist out there: http://www.dailyrecord.co.uk/sport/othe ... ed-2268180

The headline is a bit dramatic it, reads more liking toppling over, which is unavoidable in most of these vehicles if no one is there to catch you when you stop.

For extra paint protection you can get plastic coated P-Clips such as sold by SJS or can be found on ebay etc.
As Brucey says tape on the frame will also offer protection.

Here is another blog recently updated. http://www.humansinvent.com/#!/13453/i- ... f-my-head/

Could you also use a Gyro Cable to pull two brakes with one lever?

If you want to pull two brakes with one lever the Jtek DoubleControl S enables this, the jtek site. I have not used one but they have positive reviews.

I have a Bryton Rider 35, which I really like, I don't use it to navigate but to record where I have been and how fast etc. From this model you can save data from the device directly to your computer in BDX, GPX, PWX or TCX file formats. They frequently update the Bryton sport website and although it can be slow sometimes I think the recent updates have improved it a lot.

With mine I think I can upload tracks from my computer as long as they are in one of the formats mentioned above so you should be able to plot the tracks using another website e.g. http://www.bikeroutetoaster.com/.
